Lol, it seems the Windows 10 updater picks whatever screen mode it can and then just assumes it's being stretched to 16:9 by a poorly configured monitor. Running on QEMU I get an anamorphic squished display.pic.twitter.com/EY6YouMOkL

Before win7 they used 4:3, so I guess it's some improvement
4:3 is correct for 4:3 modes. Here they're spitting out anamorphic 16:9 video on a 4:3 mode, which is a huge WTF.
This assumption will display the picture properly for the majority of users - monitors that let you set the aspect are rare, and even those that have the settings are set to stretch by default, and I'd bet that less than 1% of users ever change that.
Users that care about this are also rare, and those that do configure their monitors correctly, and now *they* see it wrong.
